obama kept brennan on as an adviser, and last year, when brennan became the first official to formally acknowledge that the drone program even existed, he again encountered protests. >> how many people are you willing to sacrifice? why are you lying to the american people and not saying how many innocents have been killed? >> thank you ma'am for expressing your views. we will have time for questions following the presentation. >> i speak out on behalf of tariq aziz. a 16-year-old in pakistan who was killed because he wanted to document the drone strikes. >> now, despite brennan's past notoriety, obama officially has nominated him to head the cia. this time, there's been little criticism of the decision. so, we'll watch brennan's upcoming confirmation hearings to see if any congressional critics press him on whether the obama administration is fighting the war on terror within the rule of law. which brings me to my guests for this discussion. vincent warren is executive director of the center for constitutional rights, which is dedicated to advancing and protecting the rights guaranteed
